COAL-STOVE IGNITER.

Specification of Letters Patent.

Patented May 16, 1916.

Application led Catcher 23, 1315. Serial No. 57,532.

To all 'whom t may concern:

Be it known that we, EDWARD J. lVIATHiAs, Jr., and RALPH R. LANDES, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Coal-Stove Igniters, of which the following is a. specification.

This invention relates to burners and an object is to provide a burner having connection with a stove or other heating element, for the purpose of kindli-ng or promoting combustion therein.

"Io this end the invention comprises, among other features, a burner having its point of combustion, when in an operative position, located adjacent the fuel supporting grate bars of a stove, in order that the flame emitted by the burner will ignite the fuel supported by the grate bars.

Another 4object of the invention is to provide a gas burner of the above character adapted to be positioned beneath the gratebars of a stove and designed for sliding movement, to permit the same to be drawn out of engagement with the grate-bars, so that the latter can discharge fuel supported thereby and not interfere with the operation of the gas burner.

Other objects reside in the structural siniplication of such devices, so as to render the mechanism for carrying out the several functions thereof certain and positive in their operation, and to minimize the liability of the various parts becoming out of order.

With these and` other features in view, as will appear as the description proceeds, the

invention comprises the various novel features of construction and arrangement of parts which will be fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is a vertical sectional view through a stove illustrating the application of the present invention when in an operative or active position; Fig. 2 is a similar view illustrating the inactive position of the burner comprising the invention, Fig. 3 is a top plan view of the same, a portion of the stove being shown in section, Fig. 4L is a section on the line 4-4 of Fig. 3, Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 3, burner. Y

Similar reference characters are employed to designate corresponding parts throughout the several views.

Iteferring to the drawings, a burner 10 is positioned within an ash-pit 11 of a suitable form of stove 12, the latter being provided with the usual lire-box 13 and fuel support ing grate-bars 1li, the parts being of the usual formation and therefore do not require a more specific description.

The burner 10 extends through an opening 15 formed in the wall 16 of the stove 12 and the opening is reinforced by a plate 17 provided with an extended sleeve 18 and a central bore 19 alining with the opening 15. Bolts 20, or other fastening means secure the plate 17 to the side of the stove 12.

The burner 10 comprises a tube 21 formed on the inner side thereof with an offset burner tip 22, thevlatter being located at a point beneath the grate-bars 14. The outer end of the tube 21 has suitably secured thereto a reduced extension 23 of a mixing chamber 24E, provided with suitable air intake openings 25 in the outer vertical face 26 thereof.

Fuel is admitted into the burner 10 by a fixed supply pipe 27 provided with a swivel goint 2S from which extends a horizontally movable pipe arm 29, one end 30 of which being closed by a cap 31. Tapped into the arm 29 is a relatively short pipe section 32, movable with said arm, and provided with a controlling valve 32a, formed with an operating handle 33, the inner fuel discharge end of the pipe section 32 entering the mixing chamber 24C through one of the air openings 25. By operating the valve 32a a supply of fuel can be admitted into the mixing chamber 24, to intermingle with a supply of air entering the openings 25. The resulting inflammable gaseous mixture is ignited at the burner tip 22 thereby creating a suction to increase the supply of air into the chamber 24 and thus adding or increasing the intensity of the flame at the burner tip 22, as will be obvious.

In order to lock the burner in its operative position and to facilitate in handling the same, extensions 35 are formed on the sleeve 18 and are provided with beveled faces 36 for engagement with a leaf spring 37 and Fig. 6 is a front elevation of the secured upon an offset portion 38 of the miX ing chamber casing 24. An operating handle 39 is threaded into an opening in the odset portion and retains the spring 37 in a secured position thereto. The tension of the spring 37 is of suflicient strength in its relation with the extension 35 to prevent accidental movement or displacement of the burner 10. However, when the burner is shifted to the position shown in Fig. 2 so as not to interfere with the dumping action of the grate-bars 14, the spring 37 is disengaged from the extension 35 topermit the burner to be revolved, and pulled outwardly. When in this position ashes or debris from the grate bar can not collect in the burner tip 22 and destroy the efficiency of said burner. The swivel joint 28 of the supply pipe 27 is provided so that the pipe 28 can be swung to a position permitting the burner to freely slide, without hindrance, to its eXtreme outward position, the movement of the pipe is clearly shown in Fig. 3 of the drawings.

From the foregoing the simple yet eficient method of operation and construction of the burner will be obvious, and it is to be understood that the construction shown, has been described for the purpose of rendering the principle of the device apparent, so that such changes may be made in the structural details thereof, as fall within the scope of the appended claims.

I-Iaving described our invention, claim l. In a device of the character described, a plate, a sleeve thereon, a tube passing through the sleeve and plate, a burner tip on the tube, a handle for the tube, an eXtension in the tube and forming an air chamber, and a fuel supply pipe adapted for horizontal swinging movement associated with said air chamber.

2. In a device of the character described, a plate, a tube slidably extended through the plate, a burner tip on one end of the tube, an extension on the other end of the tube, and a-movable fuel supply'pipe normally associated with the extension and capable of being swung in ahorizontal plane to permit of sliding said tube on said plate.

3. In combination with a stove .havingmovable grates, a tube slidingly supported on the stove and normally lying beneath said grates, a burner tip on the tube,and a handle for rotating the tube and sliding the same out from beneath the grates to permit the latter to be actuated.

4. In a device of the character described, a plate, a sleeve thereon, a tube passing through the sleeve and plate, a burner tip on the tube, a handle for the tube, an eXtension in the tube and forming an air chamber, a fuel supply pipe associated with said air chamber, and means contacting with the sleeve of the plate for preventing any accidental displacement of the tube therefrom.

5. In al device of the character described, a plate, a sleeve thereon having projections, a tube passing through the sleeve and plate, a burner tip on the tube, a handle for operating the tube, and means adapted to alternately engage with the projections of the sleeve for holding the tube in locked position.

In testimony whereof we aiiX our signatures.
